Problems solved by technology

Currently, the traffic scheduling policy configured on each device in the IGP domain cannot realize automatic synchronization in the domain, and the traffic scheduling policy configured on each device is difficult to realize one-point reporting based on BGP-LS
Since the PCE cannot obtain the traffic scheduling policy information configured on the routing node, the global calculation and optimization may be distorted during the global routing calculation and optimization, resulting in the fact that the forwarding path of the actual service data is different from the forwarding path calculated

Abstract

The invention discloses a flow scheduling strategy reporting method, an autonomous domain system and an SDN network system, and relates to the field of communications. The method comprises the following steps of boundary routing equipment of an autonomous domain system receiving a first flow scheduling strategy sent by the intra-domain routing equipment in the autonomous domain system, wherein a first flow scheduling strategy is configured in the intra-domain routing equipment; and boundary routing equipment uploading a first flow scheduling strategy and / or a second flow scheduling strategy configured by the boundary routing equipment itself to PCE. The method, the autonomous domain system and the SDN network system are provided. manual intervention can be reduced, and the real-time performance and accuracy of global optimization calculation are guaranteed, so that the centralized automatic adjustment of the flow can be realized. Expansion is carried out on the basis of the existing OSPF / IS-IS protocol, and implementation is easy. Centralized scheduling is guaranteed, the consistency of the simulation result and the actual flow forwarding behavior is achieved, and the flow scheduling and optimization capability of an operator in the network can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method for reporting traffic scheduling policies, an autonomous domain system and an SDN network system. Background technique [0002] Under the SDN (Software Defined Network, software-defined network) network architecture, PCE (PathComputation Elementation, Path Computation Element) is the implementer for implementing centralized calculation of optimized paths. At present, the BGP-LS protocol is used to transmit routing node and link information in the IGP domain to the PCE, mainly including Node, Prefix, Adjacent Link and other information. Based on routing node and link information, PCE can perform global route optimization path calculation. Traditional IGP (Interior Gateway Protocol, Interior Gateway Protocol) protocols include: OSPF (Open ShortestPath First) / IS-IS (Intermediate System-to-IntermediateSystem, intermediate system to intermediate system) ...
